(ie, from left to right, then right to left for the next level and alternate between). For example: Given binary tree [3,9,20,null,null,15,7], C++代码： /** * Definition for a binary tree node. Aug 11, 2021 · We have already discussed the zigzag traversal using an iterative approach, in this post we will solve it using Recursion. Recursive Approach: The idea is to traverse the tree in a Level Order manner but in a slightly different manner. We will use a variable flag and initially set it’s value to zero.

With this, we can control which row we insert into our matrix. Yet when we .push() into the array, we are inserting a value at the end of it. So if we think of rows and columns in a matrix, it inserts left to right. We can take advantage of this, inserting characters of our input string in a zig-zag pattern. So how do we make this work?Binary Tree Zigzag Level Order Traversal. Given a binary tree, return the zigzag level order traversal of its nodes' values. (ie, from left to right, then right to left for the next level and alternate between).
